在本地级别停止 SoundPlayer 循环

发布于 2024-09-03 06:36:31 字数 976 浏览 3 评论 0原文

我正在努力设置一个警报,该警报会作为对话框弹出,其中包含用户可以选择的多个声音文件选项。我遇到的问题是在本地级别创建一个声音播放器,我可以用按钮关闭它。我遇到的问题是,当我关闭表单时,声音不断循环,因为按钮单击事件中不存在 SoundPlayer。

这就是我所拥有的:

 void callsound()
    {
        if (SoundToggle == 0) // if sound enabled
        {

            if ((SoundFile == 0) && (File.Exists(@"attention.wav")))
            {
                System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"attention.wav");
                alarm.PlayLooping();
            }
       if ((SoundFile == 1) && (File.Exists(@"aahh.wav")))
            {
                System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"aahh.wav");
                alarm.PlayLooping();
            }
     }

private void button1_Click(object sender, EventArgs e)
    {
        //alarm.Stop();  Only works if SoundPlayer declared at class level
        this.Close();
    }

有没有办法通过声明我所在的 SoundPlayer 实例来完成我想做的事情?或者有没有办法在类级别声明它,并且仍然能够根据用户设置更改声音文件?

I'm working on setting up an alarm that pops up as a dialog with multiple sound file options the user can choose from. The problem I'm having is creating a sound player at the local level that I can close with a button. The problem I'm having is that the sound keeps looping when I close the form because the SoundPlayer doesn't exist within the button click event.

here's what I have:

 void callsound()
    {
        if (SoundToggle == 0) // if sound enabled
        {

            if ((SoundFile == 0) && (File.Exists(@"attention.wav")))
            {
                System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"attention.wav");
                alarm.PlayLooping();
            }
       if ((SoundFile == 1) && (File.Exists(@"aahh.wav")))
            {
                System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"aahh.wav");
                alarm.PlayLooping();
            }
     }

private void button1_Click(object sender, EventArgs e)
    {
        //alarm.Stop();  Only works if SoundPlayer declared at class level
        this.Close();
    }

Is there a way I can do what I want to do by declaring the SoundPlayer instances where I am? Or is there a way to declare it at the class level, and still be able to change the sound file based on user settings?

为什么这是一个问题?无论如何,SoundPlayer 不支持同时播放多种声音。将其移至类范围,重写 OnFormClosing 事件,问题解决。

public partial class Form1 : Form {
  private System.Media.SoundPlayer alarm;

  protected override void OnFormClosing(CancelEventArgs e) {
    if (alarm != null) alarm.Stop();
  }
}

Why is this a problem? SoundPlayer doesn't support playing more than one sound at the same time anyway. Move it to class scope, override OnFormClosing event, problem solved.

public partial class Form1 : Form {
  private System.Media.SoundPlayer alarm;

  protected override void OnFormClosing(CancelEventArgs e) {
    if (alarm != null) alarm.Stop();
  }
}

您可以尝试:

SoundMixer.stopAll();

SoundMixer.soundTransform = new SoundTransform(0);

SoundMixer 类控制全局声音,因此它应该停止同一安全沙箱中的所有内容。

You can try:

SoundMixer.stopAll();

or

SoundMixer.soundTransform = new SoundTransform(0);

The SoundMixer class controls global sound, so it should stop everything in the same security sandbox.

使用 Powershell,我正在播放 .wav 文件,并使用以下命令开始重复循环:

$Playwav = new-object ('Media.SoundPlayer') $playpath1 
$Playwav.PlayLooping()

我通过运行部分 (F8) 停止了 Powershell IDE 内的循环:

$Playwav = new-object ('Media.SoundPlayer') $playpath1 
$Playwav.PlayLooping()
$Playwav.stop()

FWIW,我的示例中的 .wav 是 FPS Doug takethatbitch.wav。所以失控的循环让我笑了。

希望这有帮助。

Using Powershell, I was playing with playing .wav files and started a repeating loop using the following:

$Playwav = new-object ('Media.SoundPlayer') $playpath1 
$Playwav.PlayLooping()

I stopped the loop inside Powershell IDE by Run Section (F8):

$Playwav = new-object ('Media.SoundPlayer') $playpath1 
$Playwav.PlayLooping()
$Playwav.stop()

FWIW, the .wav in my example was FPS Doug takethatbitch.wav. So the runaway loop made me laugh.

Hope this helps.
